Some populations are probably larger than others, but not to a substantial degree; the three localities in that table yield very similar results overall. I'm trying to get access to Pooley & Gan (1976) to see what kind of morphometrics they have. I will also look into any research on morphometrics of the kruger population. Yea, honestly its probably just a rumor about kruger, but based on other reptiles, there would be some variability in size, where was gustave from? www.iucncsg.org/365_docs/attachments/protarea/907d4ded022a4ddefe525f89ee64b150.pdfAccording to this site, its the lake chamo crocs of ethiopia that get the largest |

From what I can tell, male Nile crocs are about 527 kg average; this gives us about 4.25 for the male-female size ratio

While pooley & gan 1976 was a pretty interesting article, it has no morphometric data of a 250kg female, so i am incredibly baffled as to why they cite it in part for that figure on wikipedia.
The ethiopian niles are definitely deserving of further study, i can't seem to find alot on them, though that is really interesting.

Look, I'm not a thresher shark expert, but they just don't strike me as a big game predator, which you kind of need to be to tackle another big animal. They hunt small fish and even then they don't kill them with their mouths, they stun (kill?) the small fish with their amazing tail, and then gobble them up. They seem shy and retiring, younger ones get absolutely destroyed by seals (granted, they are heavily outweighed). While their teeth are not all that small and seem somewhat formidable, their mouths are comparatively small compared to the typical lamnid or requiem shark. They are known for speed/explosiveness, so that is likely an advantage, along with their size advantage over the croc.
I don't know if the female croc will be big enough to do serious damage, but I'm skeptical the thresher could really injure the croc either.

Ah, okay. So you see this as somewhat of a stalemate?

Yes, most likely.
